It states that it blocks line of sight. Is it safe to assume it blocks line of sight for both side right?

You cannot sit in the smoke area and shoot out of it right?

When does it dissappear? At the end of the round? or until the next activation of the model who placed the effect (because that's ridiculously long)

Last thing for clarification. Smoke only blocks line of sight and does not constitute as occupied space so the Rogue can teleport (potion) in, out, and though spaces affected by smoke correct? Can the teleport also go through walls? (so long as he has an unoccupied space to reappear to?)

On the card it clearly says that you need line of sight to the field you want to teleport to.
